将日历字符串转换为Java中的Calendar对象 [英] Convert calendar String to Calendar Object in java

问题描述

我不会将字符串Calendar Object(calendar.toString())转换为Calendar对象.我尝试了此解决方案，但它在控制台中显示的日期是"2017年12月5日"，而不是"2017年2月2日".

I wan't to convert a string Calendar Object (calendar.toString()) to calendar object. I tried this solution but it show in console the date of the day '12-05-2017' not '02-02-2017'

字符串日历对象格式:

java.util.GregorianCalendar [time = 1485993600000，areFieldsSet = true，areAllFieldsSet = true，lenient = true，zone = sun.util.calendar.ZoneInfo [id ="Africa/Casablanca"，offset = 0，dstSavings = 3600000，useDaylight = true，transitions = 102，lastRule = java.util.SimpleTimeZone [id = Africa/Casablanca，offset = 0，dstSavings = 3600000，useDaylight = true，startYear = 0，startMode = 2，startMonth = 2，startDay =-1，startDayOfWeek = 1，startTime = 7200000，startTimeMode = 0，endMode = 2，endMonth = 9，endDay = -1，endDayOfWeek = 1，endTime = 10800000，endTimeMode = 0]]，firstDayOfWeek = 2，minimalDaysInFirstWeek = 4，ERA= 1，YEAR = 2017，MONTH = 1，WEEK_OF_YEAR = 5，WEEK_OF_MONTH = 1，DAY_OF_MONTH = 2，DAY_OF_YEAR = 33，DAY_OF_WEEK = 5，DAY_OF_WEEK_IN_MONTH = 1，AM_PM = 0，HOUR = 0，HOUR_OF_DAY = 0，MINUTE = 0，SECOND = 0，MILLISECOND = 0，ZONE_OFFSET = 0，DST_OFFSET = 0]

             Calendar calendar = GregorianCalendar.getInstance();
             calendar.setTime(new Date("2017/02/02"));
             System.out.println("calendar : "+calendar.getTime());
             try {
                 GregorianCalendar gc = new GregorianCalendar();
                 DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
                 System.out.println("calendar : "+calendar.getTime());
                 gc.setTimeZone(TimeZone.getTimeZone(calendar.toString()));
                 System.out.println("tme zone : "+gc.getTimeZone());
                 System.out.println("calendar : "+calendar.getTime());
                 System.out.println("calendar : "+calendar.toString());
                 System.out.println(formatter.format(gc.getTime()));
             }
             catch(Exception e) {
                 //If exception, return server TimeStamp
             }

推荐答案

感谢@Ole，我终于找到了解决方案并且可以使用.

Thanks @Ole , I finally found the solution and it works.

             Calendar calendar = Calendar.getInstance();;
             calendar.setTime(new Date("2017/02/02"));
             String[] ds = calendar.toString().split("=");
             String[] ds2 = ds[1].split(",");
             try {
                 Calendar cal = Calendar.getInstance();;
                 DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
                 cal.setTimeInMillis(Long.valueOf(ds2[0]));
                 System.out.println(formatter.format(cal.getTime()));
             }
             catch(Exception e) {

             }
